Monochrome palette
Pewter Ridge
Five stops tuned to sit together without fighting — #005f66 ink anchors the set, #7cd2db opens it up, and #008c96, #37a8b2, #5fb5be cross the middle in a triadic arrangement. Pewter Ridge suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
